Class MultiGeoPointValues

java.lang.Object
org.elasticsearch.index.fielddata.MultiGeoPointValues
Direct Known Subclasses:
GeoPointScriptDocValues
public abstract class MultiGeoPointValues extends Object
A stateful lightweight per document set of GeoPoint values. To iterate over values in a document use the following pattern: 
   GeoPointValues values = ..;
   values.setDocId(docId);
   final int numValues = values.count();
   for (int i = 0; i < numValues; i++) {
       GeoPoint value = values.valueAt(i);
       // process value
   }
The set of values associated with a document might contain duplicates and comes in a non-specified order.
